          A Recommendation for IPv6 Address Text Representation


   As IPv6 deployment increases, there will be a dramatic increase in    the need to use IPv6 addresses in text.  While the IPv6 address    architecture in Section 2.2 of RFC 4291 describes a flexible model    for text representation of an IPv6 address, this flexibility has been    causing problems for operators, system engineers, and users.  This    document defines a canonical textual representation format.  It does    not define a format for internal storage, such as within an    application or database.  It is expected that the canonical format    will be followed by humans and systems when representing IPv6    addresses as text, but all implementations must accept and be able to    handle any legitimate RFC 4291 format.
